You have two video concepts for a Medicare Advantage enrollment campaign. One speaks directly to seniors about their health needs. The other addresses adult children who manage their parents' healthcare decisions. Both scripts feel right, but you can only afford to produce and run one at scale. Which audience responds better, and which specific moments in each video actually drive enrollment intent?
Why this matters
Medicare marketing budgets are tight, and production costs add up fast. Caregivers and seniors process health information differently. Seniors focus on benefits and provider access. Adult children worry about cost, coordination, and whether Mom will actually use the plan. Testing both audiences before you commit to a full campaign tells you which creative direction will perform, and where to trim or extend each version.
How to do it
You'll recruit two separate panels, show each group the video concept aimed at them, and capture second-by-second facial coding data while they watch. Then you compare engagement peaks, confusion signals, and stated intent across both groups. This workflow assumes you have rough-cut video (even animatics or voiceover slides work) and a week to field the test.
1. Define your two audience panels
Recruit 50-75 people per panel. Panel A: adults 65+ who are Medicare-eligible and have switched plans in the past three years or are currently shopping. Panel B: adults 35-60 who have made healthcare decisions for a parent in the past year. You need recent decision-makers, not people who might someday care about Medicare.
Use screening questions that filter for real behavior. "Have you compared Medicare Advantage plans in the last 12 months?" or "Have you helped a parent enroll in a Medicare plan?" Work with a panel provider that can deliver these specs, or use your CRM and email list if you have the volume.
2. Prepare your video and survey flow
Upload both video concepts to your testing platform. Seniors watch the senior-targeted version, caregivers watch the caregiver version. Keep videos under 90 seconds if possible. Longer videos lose attention, and you'll see dropout in your data.
After each video, ask three to five questions. "How likely are you to request more information about this plan?" (0-10 scale). "What was the main benefit you remember?" (open text). "Did anything confuse you or feel unclear?" (open text). Keep the survey short. You want completion rates above 85%.
3. Collect facial coding data during playback
EmotionTrac Audience captures second-by-second facial expressions using FACS (Facial Action Coding System) while panelists watch your video. Participants opt in and enable their webcam. The system tracks engagement, confusion, positive affect, and negative affect frame by frame.
You'll see exactly when each audience leans in or checks out. If your caregiver video mentions "24/7 nurse hotline" at the 32-second mark and engagement spikes, that feature matters. If seniors show confusion when you introduce a mobile app at 48 seconds, you know that segment needs work or should be cut.
4. Compare emotional response curves between audiences
Export the aggregated emotion timelines for both panels. Look for divergence. Does the caregiver group stay engaged through cost-comparison segments while seniors drop off? Do seniors respond positively to testimonials from peers, while caregivers prefer data and plan details?
Pay attention to confusion spikes. If one audience shows sustained confusion during a key value proposition, that message isn't landing. You can't fix unclear messaging with better media buying.
5. Cross-reference emotion peaks with survey responses
Match high-engagement moments to the benefits people recalled in open-text responses. If caregivers show peak positive affect during the "coordination of care" section and 60% mention care coordination unprompted in their recall question, you've found your hook.
Check intent scores against emotional response. If one panel shows higher engagement throughout but lower intent to act, the creative is entertaining but not persuasive. If another panel shows moderate engagement but high intent, the message is clear and the offer is strong.
What you'll see
You'll have two data sets: one showing which audience is more receptive overall, and one showing which specific messages work for each group. Often, you'll find that one audience has a clearer path to conversion. Caregivers might respond to convenience and cost transparency, while seniors need reassurance about doctor networks and prescription coverage.
Sometimes you'll discover that both audiences engage, but at different moments. In that case, you might produce two shorter versions, each trimmed to the high-performing segments for its audience, rather than one 90-second spot trying to serve both.
Use the emotion timelines to guide your edit. Cut or rewrite sections that generate confusion. Extend or emphasize sections that generate positive affect and high recall. If your call-to-action gets low engagement, test a different offer or placement.
Common questions
How many panelists do I need per audience to get reliable data?
50 completions per panel gives you directional insight. 75-100 per panel gives you confidence to make production decisions. If you're testing multiple video variants per audience, budget 50+ per variant. Smaller samples work for early-stage concepts, but don't bet a six-figure media buy on 20 responses.
Can I test the same video on both audiences instead of creating two versions?
Yes, and you should if you're unsure whether to differentiate messaging at all. Show the same video to both panels and compare their emotional response and intent scores. If both groups respond similarly, you can run one creative. If responses diverge sharply, you have evidence that separate creative is worth the investment.
What if seniors show lower engagement overall but higher intent to enroll?
Seniors are often less expressive on camera, and they process healthcare information more deliberately. Look at intent scores, recall accuracy, and confusion signals rather than raw engagement levels. If they remember your key benefits and indicate intent, the video is working even if the emotion curves are flatter than the caregiver group.
